Currently in the process of assembling an Extreme Flight 40% Extra. Dreamt for a long time to fly a model of this size. I've been flying 50cc conversions on a Hacker A80-10/170A ESC for a couple of years so this is a step up. Will report back on static testing in 2 to 3 weeks time.

p.s. quick hello to Bruce...so good to see someone start an RC channel that cuts through the BS and scientifically evaluates products. Thanks for you efforts and keep it up. Several of us from Fleet in the UK have subscribed.

I haven't compared the price Bruce but I don't doubt its more expensive. I don't have an option though. At my main flying field we are limited to 82db for IC powered models. Electric models are not noise tested but as this is large so I did run it past the club committee before starting the project.

Regarding field charging. No. Not at the moment but I'll probably buy a Digital Inverter/Generator in the near future but I would also need a couple more chargers. I only have one set of lipo packs at the mo. The 30C Flightmax 6S5800 and 2S5800 packs.

Very nice model, and great flight! I will certainly be following this thread.What are fully aerobatic flight regime times like?What are your charge times like?I am thinking of electrifying a 60 size GP Super Skybolt bipe. My largest motors will swing around a 12" prop, and I am concerned about the lighter weight in the nose.Bryan
